- Reduce barriers for learning these tool
- Enable participation from diverse stakeholders
- Solicit feeback from under-resourced communities
- Builds trust through transparency
DANTE
Data Analysis Toolbox for Environmental Research
Overview
- Collaborative open-science platform developed by USACE, ISciences, Columbia’s CIESIN, and CASE International
- Accelerates multidisciplinary environment-security applied research
- Bridges political science, social science, geography, environmental sciences, and defense communities
TOPS-SCHOOL
ScienceCore Heuristics for Open Science Outcomes in Learning
Overview
- NASA-funded Open Science training curriculum
- Joint effort between CIESIN, ISciences, CUNY
- Emphasizes hands-on learning with real NASA datasets
- Cloud-based learning environment/workshops (2i2c)
- Case studies using recent environmental events
TOPS-SCHOOL Case Studies
nClimGrid Explorer
Interactive Climate Data Visualization Tool
- R package and Shiny web application for NOAA nClimGrid-Daily dataset
- Funded by ESIP Lab grant program
- Provides open-science tools for climate and social vulnerability analysis
exactextractr Package
High-Performance Zonal Statistics for R
Overview
- Fast and accurate zonal statistics extraction from raster data
- Orders of magnitude faster than competing methods (raster::extract, velox, ESRI, QGIS, GRASS, rasterio)
- Implements precise algorithms for area-weighted statistics
- Coverage fraction calculations for accurate area-weighted statistics
Water Security Indicator Model (WSIM)
Overview
- Global water security monitoring and forecasting system
- Operating continuously since April 2011
- Monthly reports with 1-9 month lead-times
Current Status & Future
- Open source code base
- Monthly regional blogs posted on our site
- Detailed reports available via ISciences
- Vision: Open cloud-based version for public access
WSIM
- Return period methodology (3-40+ year events)
- Quarter degree resolution
- Five severity categories: abnormal to exceptional
- Depicts both deficits (red) and surpluses (blue)
- Purple shading indicates concurrent deficit/surplus
- Data Source: ECMWF Reanalysis v5 (ERA5)
- Baseline Period: 1981-2020 (satellite era focus)
- Forecast Model: NOAA CFSv2 ensemble forecasts
- Composite anomaly index based on soil moisture, ET deficit, runoff, and blue water
